I am experimanting with texturing simple objects. My idea is to use very small textures. So I manually resized and moved the UV coordinates to be inside the pixels. You can see on the screenshot I have uploaded.
Unfortunately they do not seem to update. I have zero idea why, any hints or tips will be appreciated.
[Edit]: I have put all obj faces that should be red over the red in the texture (neatly arranged without overlapping). I have moved all the faces that should be black on the top (this time I did not arrange them as it did not help with the red).
I expect all front and back of the cross to become red and the sides to be black.
